Public bug reported:
On my pi3 I have an image with the ubuntu-core snap rev 354 and I get
the following netplan configuration file after the first boot:
ubuntu@localhost:~$ cat /etc/netplan/00-initial-config.yaml
network:
version: 2
ethernets:
all:
match:
name: "*"
dhcp4: true
This generates the following .networkd file
ubuntu@localhost:~$ cat /run/systemd/network/10-netplan-all.network
[Match]
Name=*
[Network]
DHCP=ipv4
If I look now at the output of networkctl I see it also tries to manage
my mlan0 device which is a WiFi one and should be managed according to
the netplan rule:
ubuntu@localhost:~$ networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier configured
5 eth1 ether no-carrier configuring
6 eth0 ether routable configured
7 mlan0 wlan no-carrier configuring
In summary, the networkd generator inside netplan currently does not
limit the generated .network file to tell networkd to only look at
ethernet devices but rather tell it to control every device available on
the system.
Expectation: Specifying a wildcard rule in a netplan configuration file
for ethernet devices should tell the configured networking system to
only consider ethernet devices and nothing else.
